The average cost to install solar on a home in Arizona is $3.99 per watt, with about 80 percent of systems installed for $2.64 per watt to $4.72 per watt. This is lower than the average solar cost in the Mountain Region of $4.05 per watt.
The average size of a solar system in Arizona is 8.0 kilowatts, which would cost around $31,900 without any federal, state, or local incentives.
1 kilowatt of solar PV in Arizona produces an average of 1,720 kilowatt-hours of electricity per year, so a 8.0 kilowatt solar system would generate 13,757 kilowatt-hours of electricity every year. An average household in Arizona uses 12,333 kilowatt-hours of electricity in a year.
With an average state electricity price of 13 cents per kilowatt-hour, this solar system could save a household in Arizona $1,757 each year. At this rate of annual savings, the system could pay for itself in about 18 years assuming no additional system expenses. This is less than the expected 30-year lifespan of a typical solar panel.
